Scotch-Weld™ Pipe Sealant PS65 is a single component, low strength, anaerobic pipe sealant. PS65 is a very high viscosity, thixotropic pipe sealing paste possessing high lubricity. PS65 cures when confined in the absence of air between close-fitting metal surfaces. PS65 is formulated to lock and seal medium to coarse, straight and tapered pipe threads on pipes of diameters from 15mm to 80mm. PS65 prevents vibration loosening and leakage through the pipe threads. PS65 gives low strength break and prevail torque on assembled joints, thus enabling easier disassembly and servicing, which is further helped by the lubricity of PS65. PS65 will give rapid pressure seal (after 20 minutes).
